NEEDLE-THREADING DEVICE.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed July 30, 1912. Serial No. 712,322.

To all whom it may concern Be it known that I, NOEL DUPUIS, a citi- Zen of the United States, residing at Aberdeen, in the county of Ghehalis and State of Washington, have invented a new and useful Needle-Threading Device, of which the following is a specification.

This invention relates to an improvement in needle threading devices for sewing machines.

The primary object of the present invention is to provide a needle threader for sewing machines which will be supported adjacent the needle at all times, and which while not in use, will normally remain away from the point of the needle.

With the foregoing and. other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings, Figure 1 is a perspective view showing the device attached to a sewing machine. Fig. 2 is a detail view partly in section showing the manner in which the threader projects through the needle. Fig. 3 is a perspective view of the device removed.

In the drawings, 10 designates a post the upper terminal of which is provided with the loop 11 which embraces the screw 12 of the needle post 14. This post 10 is supported rigidly being held by said screw, the lower terminal 15 of the same being 01f set from the body portion 10. A coiled spring 16 is secured to the OH set terminal 15 of said post, the loop 17 of said coiled spring being rigidly secured to the post. The coiled spring 16 is of such a length that when the same is extended its lower terminal 18 may be brought to a position adjacent the eye of the needle. The thread engaging pin 19 is supported by the collar 21 which is secured at the lower terminal of the coiled spring 16, said thread engaging member 19 being formed with the looped terminal 20 which engages the thread to draw the same through the eye of the needle.

When it is desired to thread the needle, the operator grasps the lower portion of the coiled spring, drawing the same downward and toward the point of the needle. The thread engaging member 19, is then passed through the eye of the needle and the looped terminal 20 of said thread engaging member brought in contact with the thread. The member is then drawn through the eye of the needle and the thread with it. After the needle has been threaded, the coiled spring is allowed to assume its normal position attention being called to the fact that the normal position of the thread engaging member, is above the needle, therefore there is no danger of the needle engaging member coming in contact with the hands of the operator, or goods which is passing beneath the presser foot of the machine.

The many advantages of a construction of this character will be clearly apparent as it will be noted that it may be easily and economically manufactured and that the same may be readily attached to a machine without altering the construction of the same.

What is claimed is In a needle threading device for sewing machines, a bar one end of which is rigidly connected to the needle post of a sewing machine, the other terminal of said bar being olfset, a coiled spring, one end of which is rigidly connected to said. ofi'set terminal, a collar rigidly connected to the other end of said coiled spring, a horizontal thread engaging member supported by said collar, said thread engaging member being formed wit-h a loop terminal adapted to project through the eye of the needle to engage and draw the thread therethrough.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

NOEL DUPUIS.
